KEW6315 - 2 -

Feature

This is a Clamp-type Power Quality Analyzer that can be used for various wiring systems.

It can be used for simple measurements of instantaneous/ integration/ demand values, and also for

analysis of harmonics and events related to power quality and for the simulation of power factor

correction with capacitor banks. Moreover, it can display waveforms and vectors of voltage and current.

Data can be saved either in the SD card or the internal memory, and can be transferred to PC via USB,

or in real time via Bluetooth communication.

Safety construction

Designed to meet the international safety standard IEC 61010-1 CAT.IV 300V/ CAT.III 600V/ CAT.II 1000V.

Power quality analysis

KEW6315 is designed to meet the international standard IEC61000-4-30 Class S and can measure

frequency and r.m.s. voltage with high accuracy, and also can analyze harmonics. Moreover, it can

measure swell, dip, interruption, transient, inrush current and flicker all at once without a gap.

Power measurement

KEW6315 measures active/reactive/apparent power, electrical energy, power factor, r.m.s. current, phase

angle and neutral current simultaneously.

Wiring configuration

KEW6315 supports: Single-phase 2-wire (4ch), Single-phase 3-wire (2ch), Three-phase 3-wire (2ch) and

Three-phase 4-wire.

Demand measurement

Electricity consumption can be easily monitored so as not to exceed the target maximum demand values.

Waveform/ vector display

Voltage and current can be displayed by waveform or vector.

Saving data

KEW6315 is endowed with a logging function with the preset recording interval. Data can be saved by manual

operation or by specifying date & time. Screen data can be saved by using the Print Screen function.

Dual power supply system

KEW6315 operates either with AC power supply or with batteries. Both dry-cell batteries (alkaline) and

rechargeable batteries (Ni-MH) can be used. To charge the rechargeable battery, use the charger which is

manufactured by the same company as the batteries. In the event of power interruption, while operating with

AC power supply, power to the instrument is automatically restored by the batteries in the instrument.

Large display

TFT color display with large screen.

Light & compact design

Clamp sensor type, compact and light weight design.

Application

Data in the SD card or the internal memory can be saved in PC via USB. Analysis of the downloaded

data and instrument settings are possible by using the special software “KEW Windows for KEW6315”.

Real-time communication is available via Bluetooth.

Input/ Output function

Analog signals from thermometers or light sensors can be measured simultaneously with electrical power

data via 2 analog inputs (DC voltage); when any events related to power quality occur, signals can be

transmitted to alarm devices via one digital output.

KEW6315 performs recording during the selected time period at the preset intervals, and repeats

recording processes during the preset time span.

Example: When the time period is specified as above, the recording period is as follows. KEW6315 does not

record data between 18:00 and 8:00.

KEW6315 Operating procedure

KEW6315 - 12 -

Switching of displayed parameters

Basically, the Cursor Key is used for selecting an item, the ENTER Key is for confirming the

selection, and the ESC Key is for canceling the alternation. Taking the procedures in “Quick Start

Guide” as an example, Key operations are explained as follows.

Press the Cursor Key to move the blue highlight, showing the item

is being selected, over the items in blue letters. In the screen at the

left is the Recording start screen. Press the Cursor Key and move

the blue highlight on the desirable recording method, and press the

ENTER Key to confirm the selection. To quit the start guide, press

the ESC Key.

If the display of the selectable items is similar to the one shown

to the left, then the up, down, right and left Cursor Keys can be

used. Use the Cursor Keys to select the proper wiring system and

press the ENTER Key to confirm the selection. To return to the

previous screen and cancel the changes, press the ESC Key.

To alter the numbers such as Date/ Time, move the blue highlight

over digits with the right and left Cursor Keys and alter the number

with the up and down Cursor Keys.

In the screen to the left, the tenth place of the day is being selected.

The number can be increased or decreased by 1 with the up/ down

Cursor Keys. Press the ENTER Key to confirm the selection, or

press the ESC Key to return to the previous screen and cancel

the changes.

測定前の確認 Power supply

KEW6315 operates with either an AC power supply or batteries. Capable of performing measurements in

the event of AC power interruption, power to the instrument is automatically restored by the batteries

installed in the instrument. AA size alkaline battery (LR6) and AA size rechargeable battery (Ni-MH) can

be both used. To charge the rechargeable battery, use the charger which is manufactured by the same

company as the batteries. KEW6315 cannot charge batteries. If an AC supply is interrupted and the batteries have not been inserted, the instrument goes off and

all data may lost.

* Voltage of full-charged Ni-MH battery is lower than the one of the

Measurement method

Swell/ Dip/ Int/ Inrush current

Each event will be detected with the r.m.s. values in one gapless waveform and with a half-wave over-

lapping. The beginning of the waveform where the first event is detected is regarded as the start of the

event. If further events are not detected in the following waveform, the beginning of the waveform is

regarded as the end of the event. The detected event is assumed to be continued between the start to

the end of event detection.

Example: Dip event detection

*

Int events are detected in the same method.

Example: Swell event detection

*

Inrush current events are detected in the same method.

KEW6315 Transient

KEW6315 - 32 -

Transient

Voltage waveforms will be monitored at approx 40ksps, gapless, to calculate and check for transient event

every 200ms. The beginning of the 200ms period where the first transient is detected is regarded as the

start of the event. If further events are not detected in the following 200ms period, the beginning of the

period is regarded as the end of the event. The detected transient is assumed to be continued between the

start to the end of event detection.

Example: Transient event detection

Saved data

When an event occurs and is detected, KEW6315 records the type of the event, start/ end time and the

values. The following data will also be recorded. The event waveform is recorded for 200ms during the

1 sec of the data refresh period. Event waveform

Waveforms and also event data on all the chs are recorded for approx. 200ms (50Hz: 10-cycle, 60Hz:

12-cycle) at 8192 points in total. When different events occur within 1 sec, only the waveforms which

contain the highest-priority events will be recorded. However, if the same type of events occur at the

same time, the one containing the highest (deepest) values will be recorded. If the highest (deepest)

values are also the same, the one with a longer duration will be recorded. As for the channels, there is

no priority order.

Priority order: Voltage transient-> Int-> Dip-> Swell-> Inrush current

RMS variations

Voltage/ current rms value (resolution: half-cycle) variations and event data on all chs are recorded for

1 sec at data refresh.

Example: Dip detection in 800ms period:

for approx 200ms

Waveform at event start (approx. 200ms) Waveform at event end (approx. 200ms)

Data transfer

1. SD card and USB

Data in the SD card or the internal memory can be transferred to PC using USB connection or

SD card slot/ reader.

Method of transfer

USB Card reader

SD card data (file) △*1

O

Internal memory data (file) O ---------

*1

: It is reccomended to transfer the large data by use of SD card since transfering large data files by

USB requires more time than using the SD card reader. (transfer time : approx 320MB/ hour)

As to the manipulation of SD cards, please refer to the instruction manual attached to the card.

In order to save data without any problem, make sure to delete the files other than the data measured

with this instrument from the SD card beforehand.

2. Bluetooth

Measuring data can be checked on android devices in real-time via Bluetooth communication.

It is necessary to enable Bluetooth function prior to using Bluetooth communication.

(Setting No. 26: Bluetooth) Before starting to use this function, download the special application “KEW Smart” from the Internet site.

The application “KEW Smart” is available on the download site for free. (Internet access is required and

charges may be incurred.)
